Security Bulletin: Tivoli Management Framework affected by vulnerabilities in IBM JRE (CVE-2012-4820, CVE-2012-4821, CVE-2012-4822, CVE-2012-4823)

Abstract

These vulnerabilities are only applicable to Java deployments where untrusted code may be executed under a security manager (e.g. Java applets running in a web browser).

Tivoli Management Framework does not have functions that allow external attackers to upload and execute Java code. However, Tivoli Management Framework is a common framework on which the applications written by IBM and customers run. Therefore, the fix for the updated JRE is provided just in case of unknown vulnerabilities.

VULNERABILITY DETAILS:
CVE IDs: CVE-2012-4820, CVE-2012-4821, CVE-2012-4822, CVE-2012-4823

DESCRIPTION:
There are a number of vulnerabilities in the IBM JAVA SDK that affect various components (ORB, XML and JMX). The vulnerabilities allow code running under a security manager to escalate its privileges by modifying or removing the security manager. Some of the issues need to be combined in sequence to achieve an exploit.

The vulnerabilities could occur when the IBM JRE is installed as the system JRE, such that it may be used to execute untrusted Java applets or Web Start applications in a browser.

AFFECTED PRODUCTS AND VERSIONS:
Tivoli Management Framework 4.3.1

Note: Tivoli Management Framework 4.1.1 uses IBM JRE 1.3.1. IBM JRE 1.3.1 has already reached end of support. So basically, a new fix for JRE 1.3.1 is not provided by IBM and the vulnerability information is also not reported by IBM. If a customer has any concerns about these vulnerabilities, we recommend to upgrade the Framework from 4.1.1 to 4.3.1.
